When a guy is hanging out with a girl that's a "sure thing" to have sex with him, he ruins the opportunity by not verbally acknowledging her, not talking, the whole time and by not making a move. In effect making him gay.

I told him that she'd drop dome on him if he made the first move, but he messed it up by pulling a hora and not speaking to her; he ended up dropping dome on topper.
